Timeline is at the Race to the edge.
The Dragonriders of Berk was flying towards an unknown island that wasn't an island with a tribe on it. The sun was setting and the exploration was to be done tomorrow.
"Come on guys, let's make camp here." Hiccup as the lead rider said. He saw toothless laydown and he looked at the other dragons and they had the same idea. It wasn't a open area but they were surrounded by high rising trees. The twins and Snotloud had gotten some firewood and had lit it.
The twins were bickering as usual and snotloud had fallen asleep. Hiccup and Astrid had been sitting on a log in front of the fire.
" So what do you think we will find tomorrow?" Astrid asked."I don't know maybe some new dragon or something valuable." Hiccup replies.They hadn't noticed a person nearby, because it wasn't a person at all a spiritual figure how could see the real truth of people. It was hearing the flirting of Astrid and Hiccup. It had also seen the sexual desire of Hiccup.
Seeing how hard the young man was getting it made mad.It had looked closer to Hiccups memories of being with Astrid and wanting to do naughty stuff. So he was wanting to disrespect the other sex. The boy didn't know how hard it was for the females in Viking time.The same was looking at Astrid. Her longing was to be stronger and not having to be put up for a betrothal to a person she didn't like.
She wanted to be in charge and wanted to lead them.It made the spirit mad and it had magic that could change their desires to reality. It was build up a curse for them. Curses we're normally permanent for those how received them.
The couple how had now laid down together. They were laying in each other's arms and kissed each other. Astrid could feel Hiccups erection on her leggings, it's was bigger than expected.They both felt a shivers go down their spine.
They heard a ghostly voice in. the distance.
"Leav avheir deukireuk avranukform avhem. Boausan ukhall avurn inavo lavgru-mal agh lavgru-mal ukhall be ij boausan."
( I don't own Black speech of lotr. But it seems suitable for a curse. This is what is sayas.:Let their desires transform them. boy shall turn into female and female shall be a boy.)
It was a harsh voice. A guttural sounding tone.
They eminently spring up to look around. Hiccup and Astrid looked around. seeing only darkness. They then felt a searing heat to their bodies. The pain stopped them from crying out loud. As it was there, it was gone. Hiccup and Astrid collapsed on their bedrolls and fell asleep with the next few minutes.
The next morning, Hiccup woke up to the singing of birds and he saw some hair in his eyes. He knew he had cut his hair recently so it was weird to find it had grown to his neck again. But it was the length he liked. He looked at Astrid and noticed something unusual her hair had shortened around to half its length. Her braid had opened up and her hair had a more boyish style.
The others hadn't noticed this but instead called out to Hiccup.
"Hey Hiccup, look what we found." They called out. They found a cabin that saw like it had been run down. There was old pottery and shelves of books in a unknown language. It gave a scary feeling to them that they were trespassing on somethings property.
"Come on guys, let's get out of here," Fishlegs said. He was nervous about this it didn't look good.
Hiccup felt a bit as if he was sweating, his body had accepted the curse from the spirit. It had begun to shed his hair from his body making his skin softer to touch.
On the other side, Astrid was growing hair over her body. It wasn't noticeable but you could feel it.
p They packed their stuff and headed home with their dragons and made their way back to the edge.
While flying back Astrid was getting uncomfortable in her panties that were touching her sex. There is a strong urge to rub it. Hiccup was flying alongside her. In her mind, she was starting to see a picture of Hiccup if he was a female and it was her that was pounding her pussy.
It felt as if a wave of strength had come over her and made her more muscular. But it felt so right in a way picturing Hiccup sucking her cock while he was on his knees.
Her what, she thought. She didn't have a cock. Why was she picturing herself as a male? She wasn't born that way. A blush was forming on her face. She also saw Hiccup looking at her, but noted that his face was more feminine looking. His hair had grown to his shoulders.
Hiccup himself was feeling weird it was a unique tension in his stomach. His thoughts were of a cock. It was a perfect size, big enough to hold it in his svelt, sale female hands. He could almost feel the truck of slightly darker blond pubes against his face as he orally pleasured someone. He could see a male face as if it was Astrid looking down at Him. Crystal blue eyes. It was Her well him.
While she was thinking about that. Her sex had started to shift. Her ovaries had started to push down to become testicles and began the making of testosterone, her clit had begun to grow in size. and womb didn't exist anymore.
Hiccup saw a blush on Astrid's face. It seems to be that Astrid was also having the same vision.
The heat grew in his face, he knew something was off about it. His thoughts warped, he saw a male face in front of him with a growing beard and blue eyes. His feminine hands running down a well-formed six-pack and his legs spread across this males waist.
I'm not gay but this is wrong. But it gives me pleasure to see this hot male, Hiccup thought. His nethers feel wet, it was now more comfortable to sit on Toothless back. it was as if his male parts were gone, but that would not be possible, he was born male. He had to get to the bottom of this and quick. His blush had vanished they were now descending to the edge. Couldn't believe that it took more than half a day to get back.
Astrid headed to her hurt and strongly had laid down to take a nap. Her skirt was feeling unusual tight around her waist. and her panties didn't fit at all. It also occurs to her that her breast bindings felt loose.
She froze and took off her shirt. Her perfect breast was gone. A chiselled chest with a perfect amount of muscle was there now with some body hair. She saw this in the mirror. Her skirt was digging into her new waist that was considered male now. she took it off and noticed her new sex.
Why am I male and how? Was it that unknown voice in that harsh sounding language, she well he thought because of the obvious sight between his legs. This must be happening to Hiccup too. He decided to get dressed in something that would hide his new changes and found a cloak.
Back at Hiccups hut.
Toothless had curled up on his rock slab.
Hiccup could get the feeling that his clothes were now to loose on his body. And the thinking of having sex with a male was turning his head. He hadn't noticed that his bottom was changing into a more heart shape and his penis had fully retreated into his body. As his new clitoris touched his boxers. He gave a feminine moan from him.
He undid his armour and saw that his upper body had shrunk down. And his existing muscles had become less. He also watches how his nipples had grown in size. Until he had breasts the size of Astrids. His face became more striking, beautiful and female. His hands went straight to his pants and into them to check and he felt the lips of her new cunt. His smaller female finger swept over her clitoris and it gave him a sensation. It made her moan.
But how was this possible. He well She was male when she was born. Her wider hips and soft Brown hair with her nethers made her think. He heard her door downstairs open and close then lock. She got into her oversized shirt and put on her fur jacket and some loose pants with a belt that was too loose to be held up.
She saw a blonde hair guy of her fantasy was real. He was hiding under a cloak.
"Who are you?" hiccup asked. Her new feminine voice sounds sweet like Astrid did.
"Hiccup, we have a problem," A very good looking male Astrid. lowered her hood.
Astrid couldn't believe how much Hiccup had changed. His new voice was nice. It made his penis to spring into life. Hiccup from her position could see Astrid new erection and it was a pleasurable sight. It made her wet. She didn't know what came over her as she approached him.
Astrid stood taller that Hiccup know and his new strong arms wrapped around hiccups female waist. He could feel hiccups wetness through the trousers. His hands cupped her bottom.
Hiccup felt his hands but couldn't think about the erection that was against her new sex.
"May I?" Hiccup wanted. Astrid nodded. Hiccup got to her knees and pulls on her leggings and a bigger that average cock revealed itself. Even Astrids balls looked very healthy.
Taste it, a urge came over hiccup and she licked the head and a strip gave a gasp from him. Hiccup took him into her mouth. She was teasing his head with his tongue and enjoying the taste of his salty precum.
Astrid was gripping Hiccups hair. The sensation was unbelievable for her and she was slowly thrusting her in the mouth.
He heard hiccup moaning as he deep throated her. Pulling sensations her balls and he came in her mouth.
As they were doing this they hadn't noticed the other riders watching and they had their own problems.
